Mexico Banks on 50% More Anti-Dumping Revenue in 2027

Mexico's 2027 budget plan projects a 50.4% real increase in compensatory-duty revenue, even as it cuts the International Trade Practices Unit's (UPCI) real budget by 41.1%, despite the unit managing its heaviest antidumping caseload in three decades. China accounts for 46.39% of all 97 active duties, concentrated heavily in basic metals and manufactures, as Mexico deepens broader enforcement against Chinese steel and other goods ahead of the USMCA review. 

Mexico's 2027 budget plan contains a contradiction at its core: it counts on collecting roughly half again as much money from penalties against unfairly traded imports, even as it slashes the operating budget of the agency responsible for proving those cases in the first place. 

Treasury officials expect MX$2.806 billion from these import penalties next year, a 50.4% jump in real terms versus what lawmakers signed off on for 2026. Meanwhile, the proposed spending bill would cut real funding for the International Trade Practices Unit, known as UPCI, by 41.1%, even as the unit runs the heaviest dumping-case load Mexico has seen in three decades, with Chinese products drawing most of the fire.

The imbalance lands at an awkward moment. Nearly half of everything currently taxed under these penalties, 46.39%, or 45 out of 97 active measures, targets goods from China, versus just ten measures tied to US products. Basic metals and their downstream manufactures make up 61.85% of that total, a reflection of how steel, aluminum and related industries have become the epicenter of Mexico's fight against underpriced foreign competition.

Unlike blanket tariffs, these charges apply narrowly. Mexican trade law authorizes them only after UPCI investigates a specific product from a specific country, confirms it entered the market below fair value, dumping, or benefited from a foreign government subsidy, and proves Mexican manufacturers suffered real harm as a result. Once a case is proven, the Economy Ministry sets the duty; Finance's customs authorities then collect it as goods cross the border. That division matters for the budget math: the revenue lands in general public coffers, disconnected entirely from whatever Congress decides to give UPCI to keep doing the underlying casework.

Busiest Caseload in a Generation

The revenue projection tracks real growth on the ground. UPCI opened 21 new dumping probes in 2025, the highest annual count since 1994's 22 cases, and a level unseen for roughly three decades otherwise. Momentum hasn't slowed in 2026: 13 antidumping cases and one subsidy case opened through July, plus a fresh probe into Japanese flat-rolled steel in September that pushed the year's antidumping tally to 14. By the end of July, the unit had 69 separate trade-remedy matters open simultaneously, 32 new antidumping investigations, two subsidy investigations, 29 reviews of whether standing duties should be kept in place, and six reviews recalculating duty amounts.

Some of that volume reflects how Mexico counts, not just what it investigates: under WTO methodology, a single product probed across multiple exporting countries generates a separate case for each one. A cold-rolled steel investigation opened in February 2026 alone produced three antidumping cases, covering the US, Malaysia and China, plus a fourth, subsidy-focused case aimed just at US product. 

Across 2025 and 2026, the roster of goods pulled into these proceedings spans cardboard, polycarbonate sheeting, ammonium sulfate, hot-rolled steel, aluminum profiles, bicycles, ceramic tile, glass, cable, screws and US apples, alongside polyester resin, mirror glass, plastic tape and thermal paper from China.

This enforcement wave against Chinese goods extends well beyond antidumping casework. Mexico has also raised tariffs on Asian steel imports by up to 35% and locked in permanent duties on about 220 steel products, steps Beijing has publicly labeled a barrier to trade and investment, warning it retains the right to retaliate. Separately, Mexico renewed duties on Chinese stainless steel sinks for another five years this year, citing a global steel glut, even as domestic homebuilders report that existing US steel tariffs have already pushed construction costs higher.

From Investigation to Invoice

Open cases are increasingly resolving into real charges. The Economy Ministry closed out 2025 with just four final rulings, polyester resin, footwear, SBS rubber and coiled steel nails, all against Chinese suppliers. This year has already more than doubled that pace: nine final rulings issued between January and September 11 alone, covering Brazilian and Chinese soybean oil, Chinese and Malaysian float glass, canned pineapple from Thailand, the Philippines and Indonesia, more Chinese cardboard, polycarbonate and ammonium sulfate, Chinese and Vietnamese hot-rolled steel, and imported aluminum bars and profiles.

The resulting charges can run high. China-origin polycarbonate sheeting now carries a duty of US$4.2301 per kilogram. Hollow aluminum profiles pay US$1.72 per kilogram from US suppliers and US$1.93 from Chinese ones, figures consistent with the scale of underpricing UPCI has documented elsewhere in aluminum cases, where preliminary dumping margins reached as high as 152.24% for Chinese exporters, compared with 18.47% for US ones.

Mexico's current wave sits on top of a much longer institutional record. Since 1987, the country has opened 413 trade-remedy cases in total, 383 for dumping, 26 for subsidies, four safeguard actions, resulting in 244 finalized measures. Basic metals and their manufactures have anchored that history from the start, accounting for 40.7% of every case filed and 48% of every measure ultimately imposed.

The Budget Trade-off

What ties all of this together is a resourcing question Mexico's Congress will have to answer this fall. UPCI's caseworkm gathering data from producers, importers and exporters, calculating margins, proving domestic harm, and defending rulings in court and before international bodies, is what generates the revenue Finance is now counting on. Cutting the unit's budget by 41.1% while expecting collections to climb 50.4% asks the same office to sustain record output on considerably less. Whether that arithmetic holds through 2027 may determine how much of the projected windfall actually materializes.
